Study Notes
Ubiquitous Computing
- Ubiquitous computing aims to make technology disappear into the environment, making it seamless and unobtrusive.
- This contrasts with current personal computers, which are often complex and require specialized knowledge to use.
- The goal is for computers to become an integral part of daily life, like writing, which has become ubiquitous.
- Virtual reality, which creates a simulated environment within a computer, is seen as opposing to ubiquitous computing.
- Virtual reality focuses on simulating existing environments, while ubiquitous computing aims to enhance the real world.
Key Concepts
- Disappearance: As people become familiar with a technology, their awareness of it diminishes.
- Embodied Virtuality: Bringing computer-readable data into the physical world, rather than creating a separate virtual world within the computer.
- Location: Being aware of where a computer is located and adapting to its environment allows for context-appropriate use.
- Scale: Designing computers in various sizes to suit different tasks and contexts.
- Tabs, pads, boards: Different types of computers focusing on scale and integration into the physical environment. Tabs (small), Pads (intermediate), and Boards (larger).
- Active Badges: Small devices that identify themselves and can trigger actions based on their locations.
- Living Computers: Computer technology is integrated into everyday objects, like light switches, ovens, and more.
Technologies
- Computers: High-density microprocessors, flat-panel displays, and removable disks will become readily available, for example, for daily use.
- Networks: Wired (gigabit) and wireless (cellular-based) networks for fast and ubiquitous connectivity.
- Software: Changes are needed to adjust to the continuous changes in computer hardware with tabs, pads, and boards. Micro-kernel operating systems are a potential solution, allowing modular software updates.
- Displays: Flat panel displays that are compact, with high resolution.
Implications
- Privacy: Ubiquitous computing raises concerns about privacy due to comprehensive data collection.
- Information overload: Computers will make it easier to access vastly more information, potentially leading to overload and a possible decline in the value of the computer to users.
- Social Impact: This technology will likely impact social interaction and human relationships.
- Accessibility: Making powerful computing accessible to all members of society.
Summary
- Ubiquitous computing seeks to make computers disappear into everyday life, changing how technology interacts with and enhances human activity — making it more natural and less of a noticeable constraint.
